In the accompanying drawings a suitable main frame"isshown-inithe ifoi'm-ofa standard or pedestal 1 having :an upper bracket I or; arm; 2 :and a flowerbraoket'for arm 3. A horizontal :drive shaft 4=is suitably journaled in said franie andearries:aloosedrive pulley; 5 having a clutch eniember i6; co6pera-' tive with a clutch member =7 keyed sli'dably upon said shaft vhereby the shaft maybe line27, 27 in rotated byrthe pulley in a Well-known man- A fork 8 (Fig. cooperates with clutch member 7 to shift it into andout of engagenient ivith clutch member 6 as usual. Fork 8 is shown secured to" a Brod-9 slidable, in' -suitable bearings-inextensions 10, ll of frame 1 (Figs; 2, '3, '15and27 a springlQ cooperating with extension 10 and with an enlargement 9? on rod 9 (Fig. 3), serving to move said rod to release clutch member 7 from member 6. Said member may be placed in engagementvby a bell-crank lever 13 having a fork pivotally connected with enlargement 9 (Fig. 3) and pivoted at 14 upon frame 1 to be actuated by a rod 15 connected with a treadle 16 pivoted upon the base of frame 1 (Fig. 1). When the treadle is depressed the clutch member will be en gaged. A lever 17 pivoted at 18 upon extension 11 is provided with a retainer finger or projection 17 that is adapted to engage a notch 9 in rod 9 to retain said rod set against the tension of spring 12 to retain clutch members 6 and 7 engaged for operation of the machine, (see Figs. 15 and 22). When the machine is to be started the treadle 16 may be depressed to engage said clutch members and lever 17 may be manually operated to engage its finger 17 with notch 9 of rod 9 to retain said members in co-action for rotation of shaft 4 by pulley 5. Means to automatically release said clutch members to stop the machine, according to certain conditions respecting the cans and their heads or bottoms, will be hereinafter described.

This machine is particularly adapted to seam the flanges of heads or bottoms 19 to cans 20 of shape other than circular by means of seaming rolls. 21, 22 which rotate around in contact with the flange 19 of said head or bottom. Devices for supporting and rotating such rolls are well known in the art, an example of which is shown in U. S. Letters Patent No. 810,245 granted to Adriance and Calleson on January 16, 1906, and devices illustrated in the accompanying drawings are somewhat analogous to corresponding devices shown in said Letters Patent although the can feeding and controlling improvements hereinafter described may be used with rolls operated in any other appropriate manner. Both of the rolls 21, 22 are supported by similarly arranged arms and a description of one set will suflice for both, the rolls being shown on diametrically opposite sides of the can body. Each roll is. pivotally carried by an arm 23 that is pivotally carried by an arm 24 by means of interposed stud or bolt 25. The arms 24 are pivotally supported by studs or bolts 26 that are journaled in rotative head or disk 27 whereby the pairs of arms will be carried around therewith. Head 27 is shown guided to rotate around a support 28 that is secured at its upper end to bracket arm 2, which support is shown provided with annular flange 28 supporting and guiding recessed part 27 of head 27, (Fig. 13). A spring 29 connected with arm 23 and head 27 tends to spread said rolls 21, 22 outwardly. The projecting end 23 of arm 23 forced farther against the flange.

(Fig. 11") is cooperative with finger 30 projecting from a short shaft 31 journaled in head 27 and having arm 32 carrying roller 33 to coiiperate with rotative cam member 34 (Figs. 11*, 12, and 12?), for controlling the movements of said arms. Roller 35 on arm 24 is cotiperative with a master form 36 concentric with cam member 34'. The master form has a groove of shape similar to the shape of the can body and the edge of flange 19, whereby as roller 35 travels around in said groove the rolls 21, 22 will be correspondingly guided in contact with flange 19 for seaming it. Head 27 is provided with annular gear 37 in mesh with gear 38 secured on shaft 4, and cam member 34, shown in the form of a ring, is secured to or formed on annular gear ring 39 rotatively mounted on head 27 (Fig. 13). Gear ring 39 is in mesh with gear 40 secured on shaft 4. The ratio of the gearing is such as may be desired whereby head 27 will r0- tate faster than cam member 34. Vhen head 27 and cam member 34 rotate, as in the direction of arrow at (Fig. 12), the arms 23, 24 and rolls 21, 22, 35 will be carried around with said head and at the same time rolls 33 will cooperate with cam member 34 to cause the rolls 21, 22 to operate forcibly upon the flange of the can head for seaming the latter to the body. Cam member 34 has a low part 34 intermediate part 34 and high part 34 suitably disposed in extent for the roller 33 of the pair of arms 23, 24, for roller 21 and a corresponding part 34 and high part 34 for roller 33 of the other pair of arms 23, 24 for roller 22 disposed oppositely around the cam member respecting the first named set, (Fig. 12). When the rolls 33 are operating upon low parts 34 of cam member 34 the rolls 21, 22 will be spread to receive flange 19 of the can head between them. )Vhen roll 33 of the arms of roll 21 rides upon the corresponding part 34 the finger 30 will operate upon part 23 of lever 23 to cause roll 21 to advance with pressure against flange 19 and when said roller 33 operates upon corresponding high part 34 of cam member 34, said roller 21 wil lTple e roller 33 of the other pair of arms 23, 24 will cause corresponding action of roller 22 upon the flange for finishing the same. When both rolls 33 again operate on low part 34 the rollers 21, 22 will be spread to again re ceive a flange between them, and so on for successive flanges.

To feed the can bodies automatically to the seaming roll a table or disk 41 is spaced beneath said rolls and supported rigidly upon arm 3, as by a hub 42, along which table the bodies will slide on edge. Spaced above said table is a rotative body feeding turret or disk 43 having a series of peripheral receivers or pockets 44 for the can bodies, which receivers are adapted to bring the cans successively beneath master form 36, which is locate'dover the arc of the receivers, with the can heads between the spread rolls 21, 22. A circular guard 45 partially surrounds the turretxand is spaced therefrom to admit theican bodies therebetween, which 1 guard is secured upon table or disk 41, the upper portion of said guard preferably *being flared outwardly at 45" for convenientladmissionof the canlbodies (Fig.

7). The can bodies with their heads 19 thereon are successively placed in receivers 44betwee1rthe parts 45, 46. The turret '43 is rotatedstep by step to present the can bodies successively beneath imaster form 36', for which purpose 1 the Y turret is provided with a depending shaft guided in a bearing-through hub 42,-arm 3 and'braoket arm l z'and carrying atvits lower end=adisk-47 as in theigeir nular portion of member 49 isbetween two pins the disk 47 willbe-held stationary. The

rotation of disk'47 imparts astep by step r0- tation to turret 43 in timed relation to the rotationofrolls 21, 22am]. cammember 34. Member'49 'is carried by shaft-5O j ournaled iii-bearings on "the main frame, as in arm 3, and provided with agear 51 1n mesh with gear 52 onss'haft '53 journaled in suitable bearings as shown, shaft 53 having a spiral gear 54 in mesh with a 1 corresponding gear or worm55 on shaft 4. Atra point of rest of the turret-and beneath master form 36%is ate indefinitely, but n order to 31113011121111- a rest 56-for theican bodiesoperative in a recess 41 in table 4l. Rest '56 has a stem limit thedescent-of rest 56 (Fig. 6-), and at an appropriatetime rest 56 israisedto push thecanbody with its head 19- toward master form 36; Aspring 57 in bore 3 is interposed betweenstem 56 and a rod-58 slidable in said bore-and operated'by acrank arm form.

When the can with its head secured therein ispassed from the'zmaster formitwill encounter a discharging blade 68, shownattachedwto guard 45 and extending to a position behind the path ofathe cairbodies (Figs. 1, 4, 14) ,so that the can being advaxicedbythe turret will en-, counter such blade and be discharged from the turret and from the-table4l'to 'aisuit able receptacle.

Inorde'rvtoholdtheoan bodies snuglyin I l a a lateral direction in receivers 44 of turret 43 while 'the heads'are being seamed upon such bodies-apresseror plunger 69 isoperative-in' guideway 70 toward and from :"the can bodies (Fig.5), whichpresser is shown carriedtby a rod 7lppivotallyconnectedat 72 to a crank arm 73'showu carried by a bracket 74 journaledin abearing on arm 3 and hav-' ingan'arin75-to which is pivotally connected adepending'linkfi 6 having a projection 77 coiiperative, with-a cam 78 onshaft 50. Each time acan-is-brought to rest it is-posia tionedibetween resti-56and master .form 36 .and the cam 78 will cause presserorplunger 69to push'against the-can body and hold it I firmlyinreceiver 44 of turret 43 (Fig. 5), and when the head has been seamed uponthe can/body said presser will be retracted to I release the body. p 7 a As so far describedthe machine can opercally stop the niachine in case the operator should feed can bodies to the turret without'having' heads thereonthe following arrangem ents are provided. Tothe lever 17 a a control/rod 79' is pivotally conneotedat .80

which rodis slidable in abearingin arm 2 ofthemain frame, a spring :81 uponsaid rod operatingagainst a stop 82 thereon. causing said varm to operate lever 17 to release -its finger 17 from notch 9 of rod 9. Means nontrolled by the can bodies (or the absence thereof) serve torestrain movement of rod Z9. Rod 79 has, a pairof oppositely I disposedinotches 79 cohperative with forked members 6, 7 engaged for operation of the machine. Rod 79 also has a lower notch 79 adapted to be engaged by a lower cross bar 85 of a retaining member 85 shown provided with an opening 85 receiving rod 79 (Fi s. 17, 20, 23), whereby when said bar 85 is in notch 79 of. rod 79 the rod will-be retained to prevent release of finger 17 from rod 9 to retain the clutch members in engagement for operation of the machine. When the members 83, 85 do not retain rod 79 the latter will operate lever 17 by action of spring 81 to release finger 17 from rod 9 to permit spring 12 to cause unclutching of members 6, 7 to stop the machine. The operation of the members 83, 85 is caused by the presence or absence of a can body with or without a head 19 thereon in the receiver of turret 43 at a particular position, as follows. The member 83 is pivotally connected at 86 with an arm 87 secured upon shaft 88 journaled in bearings at 89. carried by arm 2. Said shaft has an arm 90 to which is pivotally connected at 91 a depending rod or member 92 reciprocative in guide 93 carried by table 41. The lower end of rod 92 is in position over the can body when the latter is brought to rest in a receiver of the turret at a position before passing between the rolls 21, 22 (Fig. 3), so that said rod may be arrested from descent into the can body in case the rod encounters a can head 19 (Fig. 18). The retaining member 85 is pivotally connected at 94 with arm 95 secured to shaft 96 journaled in bearings above the bearings 89 and having an arm 97 to the free ends of which is pivotally connected at 98 a rod or member 99 having at its lower enda foot 100 adapted to rest upon a can head or bottom 19 that is on can body 20 in the last named position of said body, said rod 99 being guided by guide 93 (Figs. 1, 3, 18). To impart reciprocative movement to rods 92, 99 at the proper time with respect to can bodies beneath the same and with resiliency so as not to injure the can heads or bottoms 19 an arm 101 is journaled upon shaft 96, which arm has spaced lugs 101 (Figs. 24, 25), and shaft 96 has a depending finger 102 located between said lugs and opposed on opposite sides by springs 103, 104 opposing said lugs for moving said finger and shaft when the arm 101 is rocked, and for permitting said arm 101 to move without moving finger 102 when foot 100 rests upon the can head. The shaft 88 also has a depending finger 105 between opposing springs like 103 and 104, between lugs 108 on depending arm 108 hanging from shaft 88. Arms 101 and 108 are movably connected at 101 108 with a link or rod 107 having a pin or projection 105 cooperative with a cam groove 106 in the cam or disk 106 carried by shaft 53. The operation of said cam causes link 107 to rock the arms 101 and 108 to cause both rods 99, 92 resiliently to be pushed toward the can head so that if the rod 92 engages the can head it will be stopped from descent. Assuming a can having a head is fed into the receiver to position at the right hand side of Fig. 3, and that said can having its head is next brought beneath rods 92, 99 the operation of the cam 106 then will cause the descent of rods 92, 99 against the can head so that rod 92 and foot 100 will rest thereon as in Fig. 18.

The limited movement imparted by said cam to arms 87, 95 by reason of the action of springs 104, will not be suiiicient to withdraw fork 83 of member 83 from notches 7 9 of rod '7 9, nor to engage cross bar with notch 79 so that rod 79 will be retained and clutch members 6, 7 will be kept in engagement. If a receiver 44 of turret 43 should be presented beneath rods 92, 99 without a can body in said receiver then the cam 106 can move the arms 101 and 108 to actuate the levers 87, 90, 95, 97 to such an extent (because there will be no obstruction to the descent of rods 92, 99), as to withdraw for: 83 of member 83 from the notches 79 of rod 79 and to cause the cross bar 85 to engage notch 79 of rod 79 to retain the rod 7 9 and prevent uncoupling of clutch members 6, 7 for continued operation of the machine, (see dotted lines Figs. 16, 17). In case, however, that a can body be fed to the receiver of turret 43 without a head upon such body then when such body is brought to rest beneath rods 92, 99, rod 92 may clescend into the can body under the influence of the operation of the cam 106 to such an extent as to draw the fork 83 of the member 83 from notches 79 of rod 79, and foot 92 will descend upon the can body (Fig. 21), suflicient to enable the rocking of the arms 95, 97', to raise the member 85 but without engaging its cross bar 85 with notch '7 9b of rod 79, whereby the latter will be released and by reason of the tension of spring 81 said rod will be moved to actuate lever 17 for withdrawing its finger 17 from notch 9 of rod 9, whereupon spring 12 will actuate said rod to uncouple clutch members 6, 7 and the machine will be stopped.

When the machine is started the can bodies having heads or bottoms thereon will be fed successively to the receivers of the turret, as at the right hand position (Fig. 3), and as said bodies are brought to position between the master form 36 and rest 56 the body will be retained, the rolls 21, at such time being spread to receive the can head therebetween. Since the head or disk 27 and cam member 84 rotate continuously the operation will be such that as both continue to revolve the rolls 21, 22 will operate upon the flange of the can head to scam it upon the can body, whereupon at the terminseam nation ne amin the rolls 21,22 il spread from the seamed can head or bottom, theoan bodyi-will begreleased. descent of o 2 nds, s e re fi tn e he W h Withdrawal, ofx resser ca,- wherenpon the turreta-will rotate. and carry the body with the seamed heada fnom. the seeming position and present a succeeding canrbodyiand head to seaming position, the finished. bodybeing discharged-by bladev 68 from theturret.
